Resistance to ageing

Long-term evaluation of a high density Uretek material indicates a design life in excess of 100 years.  More recent research indicates that Uretek Polymer is stable up to 1000 years. This is also typical of other studies provided both independently and by major raw materials suppliers indicating long term stability and durability even in unfavourable environments.

 

Chemical Resistance of Uretek Material

The resistance of the expanded Uretek polymer to chemical agents has been evaluated as a function of loss of volume following prolonged exposure, and evaluated in the following categories.

  1. Excellent resistance (loss of volume <3%)
  2. Good resistance (between 3% and 6%)
  3. Fair resistance (between 6% and 15%)
  4. Poor resistance (between 15% and 25%)
  5. Not recommended: Only concentrated nitric acid and concentrated sulphuric acid destroy the material upon contact

Resistance to ageing

The durability of Uretek material has been subjected to long-term testing at independent laboratories  - including the University of Hanover – and by the raw material suppliers who are engaged in ongoing development of polymer resins.

The Uretek material performed well under test conditions.
